I tried wesabe and mint. Mint was easier to use. However, now that you explained a little bit about your Yodlee decision, I can sympathize w/ your conclusion. It turns out to be strategically deadly wrong but given your high-mindedness, don't beat yourself up too much. You can always take comfort in the fact that you were not "Webvan" :).
To get websabe to where it was, you must have made a number of "right" decisions also so you should reviews those too. You'll be back, I'm sure, and we look forward to your next venture. good luck.
ps. do consider the whole user-experience next time. pps. I ditched mint and went back to quicken for better control of my data and mint haven't got the cash account feature to fully work yet.
